Ferryl hemoglobin and heme induce Α1‐microglobulin in hemorrhaged atherosclerotic lesions with inhibitory function against hemoglobin and lipid oxidation
Infiltration of red blood cells into atheromatous plaques and oxidation of hemoglobin (Hb) and lipoproteins are implicated in the pathogenesis of atherosclerosis. α1‐microglobulin (A1M) is a radical‐scavenging and heme‐binding protein. In this work, we examined the origin and role of A1M in human atherosclerotic lesions. Using immunohistochemistry, we observed a significant A1M immunoreactivity in
